Table view contents in 10.3

Help please. I’m writing a package in OS 10.4 wich uses the content property of table view, ie

set the content of tableView to sumstring

where sumstring is a list of lists, and tableView is a reference to the specific table. This works fine to display the content of sumstring. However, I would like to have a version of the package that works in 10.3, and I’m having a problem with finding the right sytax. I’ve tried:

append the data source of tableView with sumstring – which it appears should work in 10.3
update tableView

This doesn’t produce an error, but the table is still blank. Advice please? I’m probably missing something simple :frowning:
